Arguments
EstParam |
A list of estimated parameters from srtsim_fit function, EstParam slot if the simSRT object. |
numGene |
An integer specifying the number of genes in the synthetic data, default is 1000 |
location_in |
A dataframe with x, y, and region_label |
region_cell_map |
A dataframe specifying the cell type proportion in each region. Row: region,Column: cell type. |
fc |
A number specifying effect size for ligand-receptor pairs that mediate the cel-cell communication, default is 3 |
LR_in |
A dataframe specifying ligand and receptor pairs, containing four columns: protein_a, protein_b, celltypeA, and celltype B |
sim_seed |
A number for reproducible purpose |
numKNN |
A number specifying number of nearest neighbors with elevated gene expressin levels, default is 4 |
numSingleCellType |
A number specifying number of spots in the background pool. Gene expression count are then sampled from this background pool. |
Value
Returns a SRTsim object with a newly generated count matrix and correspoding parameters
